Windows diskpart shows these 4 disks and their partitions ok

But Aomei Partitions assistant show 2 more disks (one 20 GB one 116 GB), I have no idea of what they are !!?? 


  • @Pdf, Could you take screenshots of Windows Disk Management and Partition Assistant so that we check?
    You can press Win+R, and then run "diskmgmt.msc" to open windows disk management.
  • Hi
    here it is


    This morn I have an additional unknown 7th drive lol

  • Bump, as I had no reply...

    It changes from day to day lol, but Aomei Partition still shows me additional phantom drives...

  • @Pdf, It seems that you are using an old version. Please download the latest version to use:
    And, please still use your license code to register.
    Did you mean that your computer doesn't have disk 5 and disk 6?Could you reboot the computer to check again?
    If you still get the situation, could you send us the log folder under the installation directory of AOMEI Partition Assistant?

    AOMEI Partition Assistant Is Working...

  • @Pdf, Did you connect any external device? 
    And, please search "CMD" at the Start menu, then run "Command Prompt" as administrator. After that, please run command:
    List disk
    And then, please take a screenshot to us.

    I don't have any external storage, only a bunch of wireless peripherals (mouse keyboard headphones speakers) that arent storage...

    The diskpart list says I have 4 disks 


    AOMEI Part Assist has one more (as above)... I've ran "verify partition" on this , it says it's ok and according to read speed it looks like it'on my SATA Samsung SSD (because it's around 300MB/sec, whereas the HDD goes 150MB/sec and both NVMe are above 2GB/Sec when I execute this same check)

  • @Pdf, Sorry to reply to you late. According to the log, disk 4 is a virtual disk from the virtual machine(hyper-v). Is there a  virtual machine on your computer?
    And, you can check the Device Manager to see if there are 5 disks. 
    As for 16 MB partition, it is MSR partition. Generally, windows disk management doesn't show MSR partition.
  • Well, I've never installed any virtual stuff afaik, and device manager only shows my 4 "real" drives...
    How could I check this ??
  • @Pdf, Please right-click "This PC", then click "Manage"-->"Device Manager", select "Drives", then take a screenshot to us.

    Thx for the remote, phantom drive is  explained

    It was a XVD virtual drive, from what I've read it's linked to Xbox stuff, I do have xbox pass since not long so it should have been it

    Your support disabled it, but I've relaunched a couple Xbox pass games and behold it created new XVD drives ! Noone knows what it does exactly it seems... thanks MS^^

    But now you'll know if ever other users see them
